Advantages and disadvantages of ammeter

As we know a word meter is used with the measurement system. Ammeter is an instrument that can measure a particular quantity. As we know that the unit of current is ampere. An ammeter is ampere meter which measures ampere value. Ampere is the unit of the current so an ammeter is a meter or an instrument that measures current. Here this article gives the information about the advantages and disadvantages of the ammeter to better understand this topic.

Advantages of ammeter:

  • It is strong, portable.
  • It does not dependent on the earth's magnetic field.
  • It could be made very accurate.
  • An ammeter is used to measure the magnitude of electric current in an electric circuit.
  • Some ammeter has no hysteresis error.
  • It is used both AC and Dc measurements.

Disadvantages of ammeter:

  • It is heavy.
  • It needed multiple heavy meters to measure a different range of amperage.
  • It could not store data.
  • Heat and vibration can affect the permanent magnet.
  • It reduces the accuracy of the device.
  • The meter is subject to parallax as well.
  • It is expensive than other measuring instruments etc.
